File Manager, Side bar drop downs need to be more friendly

Hi,
No doubt CentOS Web Panel is a great alternative to CPanel and I really
enjoyed using it till date. The New File Manager in user panel is also very
good.
However, I face few issues as below:
1. Dropdown in Admin panel stops working many times, and after refresh it
works fine.
2. User Panel Login: many times it doesn't login at first time (no error as
well) and requires 2 tries to login
3. In FIlemanager of user panel, searching is not good. We are able to
search a pattern for only once, repeated search option is not available
4. WHenever I Update Mod Security Configuration, it removes the custom
rules from its lists which I think should be retained.
5. In order to allow sftp acces, I went to List Accounts in admin panel, edited customer account and Enabled SSH and updated.
With this, the DNS Zone of that account got updated with the internal IP of Google Cloud, External IP was missing completely. Then I edited the Zone manually and updated the IPs for all domains and subdomains, it started working.
This looks like a bug. Updating account should not have updated the Public IP.
Please consider these points and make necessary updates.

also i would like to see the option of folder size
and empty directory remover
and image resizer
